SHOCK-BSOEB.

Application tiled July 17,

To all whom 'it may concern.

Be it known that l, FREDERICK MESINGER, a citizen of the United States,and a resident of New York city, county of Bronx, and State of New York,have invented certain new and useful Improvements in Shockbsorbers, ofwhich the following is a specification.

rlhis invention relates to a novel shock absorber for automobiles, whichpossessesgreat resiliency, is not liable to break or bind, and isnoiseless in operation.

ln the accompanying drawing, Figure 1 is a side elevation of a shockabsorber embodying my invention; Fig. 2 a longitudinal section thereof;Fig. 3 a horizontal section through the lower part thereof; Fig. et alongitudinal section through the axle bearing, and Fig. 5 a section online 5 5, Fig. l.

To the frame or chassis 1, is pivoted at 2 the forward end of a mainbracket or arm 3, the rear end of which is forked as at l. Bracket 3, isfurnished with a cylindrical section 5 which is supported upon a pillow6, t'o which cap 7 is secured by yokes 8, the

vbase 9 of the pillow having a bearing 10 for the rear automobile axle11. By the construction described the axle is free to IThrough casing14, 15 extends'axially a lbolt 17 that is provided at its protrudinglower end with a tubular bearing 18. This bearing is by a pintle 19pivotally secured to the forked end 20 of an arm or second support 21which is straddled by fork d, and is bolted to chassis 1, at at 22 so asto torna part thereof. .Bolt 1'? is enf compassed by a strong spiralspring 23 housed within casing 1t, 15 and resting upon a metal disk orbase plate 241. At itsv upper contracted end spring 23 abuts against thelower tace offen adjustable apertured head which is moan on the bolt,the bolt in Specication of Letters Patent.

Patented Feb. 29, 11916. isis. serial No. 40,372.

` of these disks is engaged by one member of a pair of lock nuts 28mounted on the upper threaded end of bolt 17, and by means of which thetension of the spring may be regulated. A longitudinal groove 29 formedin the upper part of bolt 17, and passing through head 25, 27,constitutes a vent.

Base plate 24, is supported upon the upper Hanged end of a cup 30,accommodated within the bottom of casing 14 and charged with a berpacking 31 that surrounds bolt 17. Between cup 30 and casing 14 there isiitted a metal insert 32 through the flange of whichl the .pivots 13pass. lWithin this insert there is formed a clearance 33 within whichare received concaved shoes 34 carried by the pivots 13 and straddlingcup 30.

ln use, the jolts will cause the plunger to play within the casing sothat in this way the shocks are effectively absorbed by spring 23, itbeing of course understood that the device is duplicated so as toprotect both sides of the'vehicle.

The apparatus is not liable to get out of order, is very sensitive, andowing to the pivotal connections of the casing and plunger with theirsupports, any binding of the parts is effectively prevented.

1 claim:

1. A shock absorber comprising a frame, a forked arm pivoted thereto, anaxle bearing carried by the arm, a casing straddled by the arm andhaving a pair of protruding pivots -that are mounted in said arm, ay

plunger within the casing, said plunger having a lower protruding endthat is pivoted to the frame, and a spring within the casing that is.engaged by the plunger.

2. A shock absorber comprising a frame, a forked arm pivoted thereto,and provided with a cylindrical section, a pillow engaged by saidsection, an axle bearing supporting the pillow and adapted to tilt onthe cylindrical section at right angles thereto, a casing pivotallysecured to the arm, an in closed plunger that is pivoted to the frame,and a spring housed within the casing and engaged by the plunger.

3. A shock absorber comprising a forked frame, a forked arm pivotedthereto and straddling the forked trame. an axle bearlport, pivotscarried by said support and extending into the casing, and concaved'shoes on the inner ends of the pivots thatengage'the cup.

5. A shock absorber comprising a casing,

a plunger extending 'axiallytherethrougm n a spiral spring housed withinthe casing and engaged by the plunger, a cup beneath the spring, apacking within the cup, a ianged reinforcing member surrounding the cup,a support, pivots carried by the support and extending through thecasing and reinforcing member, and concaved shoes on the inner ends ofthe pivots that engagel the cup.

6. VA shock absorber comprising a first support, a casing, pivotscarried by the support and projecting into the casing, a sec ondsupport, a plunger pivoted thereto and extending axially into thecasing, a spiral' spring housed within the casing and engaged by theplunger, a cup beneath the spring, a packing Within the cup, and shoeson the pivots that engage the cup.
